The economy, as we understand, SO far
as the consumption Of fuel is concern
ed, Is said 10 be decidedly in favor of
petroleum; but the trouble in its use
came from the intense heat produced,
by which, or by the peculiar nature OF
the combustion, the iron of both the
furnaces and boilers began TO indicate
rapid deterioration -he1ce the return

IL is not long since we spoke of the
benefits conferred on the farmer by
the inventor. The following statement
is a good illustration of our views as
then presented. 1t is taken from our
contemporary, the Ne,o England
Farmer. "By the use Of moving ma
chimes and horse rakes and horse hay
fork, two boys in Connecticut last sum
mer cut, raked, and helped TO stow
away 100 tons of hay, while their
father was disabled from work by i'll
ness. Under such conditions a farmer
is apt to feel like ble' sing the man
who invents labor saving machinery

SUCCESSFUL MATCHING or SALMON ~
AUSTRALIA.
According 20 the Colonies and Indid,
the last experiment in sending salmon
oya to the Antipodes appears 20 have
been a great success In January, 1885,
a shipment of eggs was made by Mr..
James You'll, by desire OF the Tas-
manian Government, and the bulk of
the eggs reached the colony In good
condition, development Of the embryo
having been suspended by means Of
Haslam's refrigerating machinery.
The eggs have developed into "fry,"
and the ''fry" into "smOlts," for several
young salmon about 8 inches long
have been captured accidentally in the
Tasmanian Mersey.
LIME CARTRIDGES.
The cartridges have been found
most valuable for work in many kinds
Of stone, including granite, Portland
stone, sandstone, etc, as well az
masonry of stone or brickwork. A
block of granite weighing about four
tons, and embedded on two sides and
at the bottom in strong cement, was
recently moved easily by two shots.
In experiments for the Admiralty at
Portland, three shots of lime cartridges
got thirty tons Of stone in large mer-
charitable pieces. The cartridges were
used with great success for upward Of
twelve months in the formation of the
Copenhagen Tunnel, North London,
and they are now in use for removing
the sandstone in the excavations of
the Mersey Tunnel Railway Company,
at Liverpool.
NEW RUSSIAN CANAL.
The Russian Government has con
tracted a loan of 100000 rubles with
the firm of Hersent * Co, Paris, for
the construction of the Perekop Canal
in Southern Russia NJ. Louis Gals
siau, French engineer of Suez Canal
fame, is to be the chief engineer The
canal will establish direct communi-
cation between the River Don, the
Black Sea, and the Sea of AZov, and
will also be the medium Of connecting
several South Russian railway lines.
IL will be Of considerable strategical
importance, but its commercial signiii-
canoe will be still greater, as it will
enable coal to be brought from the
rich mines in the vicinity of the River
Don 10 the Black Sea, where their
selling price will be lower than that
Of English Goals, which, at present, are
the only kind used mt Constantinople
and the Black Sea ports.
wxNTED-AN INVENTOR.
The pita plant OF Honduras invites
the enterprise of American capital
and Yankee invention. Only one
thing Is needed and the lucky mans
fortune Is made. Mr.. Burchard, our
consul, reports that this plant which
has never been cultivated, grows spon-
taneously and in apparently mex
haustible quantities by the margin of
every river and lagoon, and, indeed,
anywhere below the altitude of two
thousand feet. It can be had for the
cost of cutting. The fiber Is suscepti-
BILE of thousand uses. The people
OF Honduras convert IL into thread for
sewing boots and shoes, and into nets,
fish lines, and cordage. The finest
hammocks and most costly are also
made of IL. The small quantities
which have been sent TO this market
have been manufactured into hand
kerchiefs. laces, ribbons. false hair, and
wigs. The difficulty Is TO decorticate
,the plant without rotting or injuriug
The fiber. The man who can do that
win be able 20 take fortune at the
flood.-N Y. Herald.
